Property value

Remarks

The TileNavPane displays either three levels of navigation elements (categories - items - subitems) or two levels (items - subitems).
In the first case, categories (TileNavCategory) are the root-level navigation elements. Each category contains items (TileNavCategory.Items), each of which in turn contains sub-items (TileNavItem.SubItems). To add new categories and access existing categories, use the Categories collection.

The reduced two-level hierarchy omits the categories level. To display the two-level navigation hierarchy,
set the MainButtonBehavior property to ShowDefaultCategoryItems and specify the root-level navigation elements (items) via the TileNavPane.DefaultCategory.Items collection, which can be accessed by the DefaultCategory property.

To manage the collection of TileNavPane's categories at design time, you can invoke the TileNavPane Designer.
